This ACT Heavy Duty Pressure Plate (SB018) is a great fit for multiple Subaru models. It's designed to replace parts from the original ACT SB9 Clutch Kit. The pressure plate uses an exclusive diaphragm design, which increases the clamp load, reduces deflection, and maximizes the clutch life. All diaphragms go through a four - stage heat - treating process for top - notch performance. With precision cover stampings, it offers rigidity and consistency. ACT's Heavy Duty pressure plates can boost the clamp load by 20 to 50 percent. They are perfect for use with street or race discs. The Monoloc, a one - piece component, is a direct replacement or upgrade for the standard two - piece wedge collar and wire ring in pull - type clutches. Its segmented retaining ring's spring tension is carefully calculated and tested for the best performance. It evenly loads the bearing and pressure plate, ensuring proper alignment regardless of driver actions or vehicle modifications. Made of hardened chrome - moly steel, it will serve you for years. The pedal effort is light to moderate, giving you confidence during hard shifts and positive engagement. It's recommended for both street and race use. All ACT pressure plates are 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability, and they come with ACT's patented Monoloc. There's a limited retail warranty, and you can follow ACT's General Installation Instructions.


Using the ACT Heavy Duty Pressure Plate is easy. First, make sure to follow ACT's General Installation Instructions during the installation process. This pressure plate is recommended for both street and race use. When driving, you'll notice a light to moderate pedal effort, which gives you confidence during hard shifts. Remember, this pressure plate is only meant to replace parts from the original ACT SB9 Clutch Kit. For maintenance, there's no need for any special treatment. The diaphragms have gone through a four - stage heat - treating process, and the Monoloc is made of hardened chrome - moly steel, which means they'll last for years. However, if you notice any abnormal noises or reduced performance, it's a good idea to check the alignment of the bearing and pressure plate. The Monoloc is designed to provide uniform loading, but any vehicle modifications or driver influence could potentially affect it. Also, keep in mind that this product comes with a limited retail warranty, so if you have any issues, you can reach out for support.
